Application filed January 28,

T0 aZZ whom it may concern Be it known that we, .ALFREo G. F. Konowsniand HENRY N. MoKAY, both citizone of the United States, and bothresidipg in the borough of Brooklyn, county of Kings, and State of NewYork, have invented certain new and useful Improve ments in Type-WritingMachines, of which the following is a. specification.

This invention relates to devices for adjusting sheets of paperpreparatory to writil'ig thereon in .typewriting machines Thepr esentinvention is particulaflyintended for use in connection with sheetswhich are provided with marginal perfo a tions, as for instance at theirends, these perforations being provided'either for. the purpose ofbinding or .forother purposes; and we provide upon a work support orsheet-adjusting plate a. series of stuns, upon which the perforations inthe sheet fit. The sheet is placed, or impaled upon the studs, and thenthe typewriting proceeds. The studs cooperate with the perforations toposition the; sheet reference to the printing line .01; the platenPreferably the studs are movable, so that after positioning the worksheet, :they mey'disnppeer or sink'out oft-he holosin'the paper. 7

i l/ here {l the invention is used in. connection with the revolulolepla iefi 'of s. front'strike writing machine there ma y be employed asheet-positioning plate or tablet extending alongthe platen, and saidplate may lie over-the top of the platen, andth'e studs may project fromthe plate. In such ma-. chine, after the sheet is positioned by means ofthe studs, the usual pressure devices may be brought into use to holdthesheet against the platen. Y

W here it is desired towrite several lines upon a Work sheet et oneinsertion in a. front strike machine, --t,he sheet may be releasedfroiuthe studs. the studs may be connected to the same key that releasesthe usual pressurefrolls, so that when the pressure rolls are cast elf,the.

studsare. projected; and vice versa.

much as the studs hold the sheet. so thatit s not liahleto becomedisplaced while the pressure rolls are still castott; but the inventionis not limited to theseadvantages. Therc'may also be provided ventingthe studs from being accidentally withdrawn or pushed down'by thepressure of the operators fingers, thereon. For this purpose, a lock maybe employed which automatically locks the studs in projectedpositions;.wh ile said key unlocks the studs or pins and causes them todrop to normal positions of disuse. The invention is not, however,limited to studs'whichslisappear; one of the principal foetuses of theinvention being the provision of studsin such relation to the print ingline of plat-en, that whena work studs by means of l t :r tew i F orthis purpose,

invention is used tin-connection sheet is impaled .on the .the sheetitself will lie in proper relation to said printing line or point. Bymeans of the studs. therefore, the sheet may be positively andaccurately adjusted. I

- Otlier featuresand advantages will hereinafter appear.

15 a perspective view of our invention shown as mounted on the platenframe of an Underwood typewriter looking from the rear of the machine.Fig. is a sectional end view in which all of the platen frame isomitted, excepting such parts as are more The shown in its operacloselyrelated to the improvement.

actuating mechanism is tive position to receive paper. Fig. 3 is asimilar end View and shows the relative position of the parts when thepositioning studs are in their normal. posit-ions. Fig. l is an enlargeddetail view of one of the means for actuating the same.

typewriting machine carries a platen frame having the two" end pieces 1and 2, connect- ,ed bya rod 4. The platen 5 is journaled lJE.-' tweentheends on shaft 6, having a fingerwheel 7:.

An inclined top paper adjustingtahle is arranged at the'delivery side ofthe platen, i in the,fom of, a,bridge-plate 8, surmounts withdraw or Inthe accompanying drawings, Figure l and adjust a sheet of thepositioning studs and The carriage frame 3 of the Underwood means forpref lthe plaiteu end extends the length thereof,

being mounted on the plat-en frame ends 1, 2, and braced at 35intermediate its ends. Bosses 9 and 10 project rearwardlyfrorn the bodyof plate 8 to form bearings for a pail of slieet'positioning or gagingstuds 11 and 12, adapted to project up through the table 8, to receivethe perforated sheets. These studs constitute in effect a gage. Thesestuds are nmrmally below the table 8, but are projected by rocking ashaft 13, which is journaled in. bearings 14, 15 and 16' at the rear ofthe plate 8. The rock shaft (actuated by a key lever 26) is providedwith downwardly-extend'ing arms 17, 18, slotted near their free ends toengage pins 19, 20, which project from the sheet-positioning studs 11and 12 near their rearward ends, whereby said studs may be operated.

\ihen the rocker arms 17, 18 are moved forwardly, the pins 19, 20 areforced thereby forwardly along the longitudinal slots 9 and 10', whichterminate in catch or detent openings 9, more clearly shown inl ig. 41.These catches retain the studs in their extreme forward positions, byengaging the pins 1.9, 20 which are forced to rock into them by reasonof the contort-ion of the coiled springs '21. Each spring 21 has one ofits ends attached tothe stud 11 or 12, and the opposite end anchored toa taper pin 22.

The positioning studs remain locked in their forward positions until thepressure rolls are restored against the. platen to hold the sheetinplace which extends around the platen. The cam'surfaces 23 in thereturning slotted arms 17, 18 then release the pins 19, 20 from thecatches, and allowthe distended springs 21 to return the studs totheirrearward positions, so they will not interfere with the advance of thesheet as the platen is revolved. i

As a convenient means for operating the rockshaft l3, we employ a crankarm 24,

- mounted'at one end thereof and connect the ducing the sheet 30 betweenthe paper shelf 33 and the platen and in fitting the holes 31, 32 of thesheet on the positioning studs 11, 12; The return of the key lever tonormal position restores the pressure rolls and swings thestudcontrolhng arms 17, 18 to releasethe pins 19, 20 from the catches 9after which the retracting springs 21 withdraw the positioning studs 11,12 as the at:iii-controllingarms swing rearwardly.

Variations nlay be .resortedflto within the scope of the invention, andportions of the improvements may be used without others.
